				impUnsubmitted Done Inline Actions There are some armv5 architectures we still support, though clang support is, at best, weak. xscale is supported, though it is likely on the chopping block armv4, armv4t, armv5, armv5te, armv6, armv6t2, armv7, armv7-a, armv7ve are also supported Also on the list for armv[45] is: arm920t, arm926ej-s, marvell-pj4, fa526, fa626, fa606te, fa626te, fa726te though some of those are on the chopping block or have been removed. armv6 documents that we support: arm1176jzf-s, generic-armv7-a, cortex-a5, cortex-a7, cortex-a8, cortex-a9, cortex-a12, cortex-a15, cortex-a17, cortex-a53, cortex-a57, cortex-a72, exynos-m1 though the last 4 are 64-bit chips nominally, only some of which support 32-bit armv7 code and we don't really support running 32-bit kernels on 64-bit platforms apart from i386, so documenting them under arm likely isn't a good idea. Also, the lists that I have here are taken from the bsd.cpu.mk comments, and is somewhat gcc centric as the list was generated back in the time of crappy arm support in clang. imp: There are some armv5 architectures we still support, though clang support is, at best, weak.
